So glad Tract scope is being used here. I love my Toric better than my Leupold. Like sitting in the Opthamologists chair " Which one is better" A- Tract , or B- Leupold ?" Now, that would get more guys in to get their eyes chacked!
All but slope shooting and ranging can be learned by participating in CMP/NRA governed high power rifle competition without need for any electronics. Slope compensation can be calculated with simple calculation from angle cosine chart and ranging via MOA or mil scale reticle ranging formula. Nevertheless, this long range course seems to be as comprehensive as it is excellent.
